How did the car get more HP and become slower in 0-60 time? The 2007 335i did the same sprint with Inside Line in 4.8 seconds....

I was thinking exactly the same thing.

It is well know that the 335i has been tested several times by multiple magazines and websites and most of the times were saying that the usual ultra conservative BMW spec sheet number of 5.2 was underrated and that the real number should be 4.8 and that number was consistently agreed among users as well.

The point I am trying to make is, I hope all the people that bought their IS's thought it was sincerely worth it. If you are coming from a Warranty Perspective, then I can completely see it but otherwise, somewhat hard to justify.

Then again that's just my opinion!

Easily bested? The tune puts it on par with the 'is' and I am not sure what Shiv is talking about when he says in statement #2 "the N55 with 7DCT" There is no such animal that I know of. And you also forget to mention the overboost the 'is' has. And you also fail to mention that Shiv also states that you shouldn't look for anymore output due to the single turbo. So I would think that the 'is' with the N54 is a more attractive car if extra HP is your thing!

A tuned 335is is the same as any tuned N54. According to dyno graphs, you will have about a 10 WHP advantage lol. The main advantage is your DCT. To each his own though, I still think its a beautiful car

10whp? Didn't you mention more in your first post? its 27 + overboost C'mon man, if you are going to take the anti-is side at least be consistant.

On par?? I am not sure you understand the difference between 293 WHP with 343 WHEEL TQ with your 7 second overboost function on a stock IS and 340 WHP with 375 TQ on a tuned N55. The moment the IS is tuned the overboost function is lost as it is a bunch a crap and is replaced by the same exact TQ numbers a tuned n54 would get.

$57k?? HAHA!! what a waste, you could buy an 07 coupe AND sedan and have more power with any tune.

ex. Late in service date 07 used CPO with 335i with a $400 JB3 will save you $27,000 over new M3 and 335is! $27k in your pocket and at least 2 years of maint/warr. is all you need before you upgrade again.

Looking forward to the TT M3 sedan, that will be worth the money.

You talk about saving money here and saving money there, mentioning both the 'is' and m3, yet you say the TT M3 sedan will be worth the money. A car you have not even sat in, is worth the money??? Your post is stupid on so many levels!!!

BTW, 'N55 w 7 DCT" is a 2011 135i. Simple research is key... lol

I understand the difference between WHP & Torque, I just think you are mixing up the tuned & non-tuned numbers. So keeping it simple, non-tuned = 27hp & 39 tq adv for the 'is'
Talking about both being tuned was never a topic of conversation because the N54 numbers were not mentioned. How much gain would I get for $850?

And yeah, forgot about the 135i with the 7dct, probably because we were discussing the 3 series.... my bad!

Its 55,400 for a base M3 sedan. And be real, who is going to get their M3 totally optionless unless you intend on strictly racing it.

ah yeah. Maybe I was thinking ED and after the dealer knocked off a few thousand. In any case, $57k is nuts. not sure what you really need in a well-equipped BMW like any M car but I don't see how skipping iDrive or this-and-that option means helps you "strictly race."

I think the problem is that you're comparing a tuned N55 335i to a stock iS. Are you saying the iS can't be tuned? A tuned iS will still retain its advantage.
It's worthy every penny to me. But, I do agree with you though, it's not for everybody.

While PROcede currently runs lower boost numbers for the N55, a PROcede tuned N54 335i will have the EXACT same numbers as a PROcede tuned 335iS. iS gets the benefit of extra cooling which would be helpful in keeping it going for longer, but does not offer any power advantage. They are both running the N54, and the PROcede will arrive at the same peak boost for each.

Overboost doesn't do anything for a tuned 335iS. Not being anti-iS here, but it's a fact that a PROcede runs far higher boost than even the overboost function. So activating it wouldn't change power/torque at all.

So...where is the IS gains? improvements over it?

Same question here... and even the quarter-mile time and trap speeds are very marginally better... seems odd. I'm surprised so few people have commented on that.

I am glad that at least someone on here knows what they are talking about...

Thanks but I don't live everyday worrying about racing a tuned 335i or any other car. The extra hp and cooling, exhaust, dct (which I got for free after rebate),overboost, functional diffuser,pedals and other touches are worth every cent. Plus, I got a very SIZEABLE discount off the msrp, so am very happy

You gonna go the V5 soon? Looks like Shiv has done an amazing job...again! Can't wait to try out the ignition timing based traction control.

Not a 335iS hater here, it's an excellent car - glad to see BMW are aware that the N54 is undertuned in stock form! Plus, the 313 rims are the SEX I understand that a lot of people don't want to mess around in their engine bays so the iS is a logical choice. It's a shame the model isn't available in Australia.

Just trying to make it clear that tuning means that the advantages brought upon by the iS are hardware based only.

Forgot about the wheels

Sorry it's not available over there It's a nice car. Once I drove it and listened to that exhaust note and saw the other features on the car, I knew I had to take it home

I've been waiting to see some thorough testing of the 335is on a track. I have an E92 335i with a DINAN stage 1 tune, so I've been curious as to how my car stacks up. Having been to the track now on a few occasions, I know that the numbers posted on any given day are subject to any number of variables. That said, I'm happy to see that my mild stage 1 tune can out perform all the 335is numbers I've seen posted (in a straight line, at least).

I think the 335is has a place, and I think it's a beautiful car. Knowing what I know, I would much rather own an M3 if it came down to a decision between the two. Just my opinion.
